Heart surgery fluid puzzle: new ultrasound trick may help doctors decide

NCT ID NCT06645327

First seen May 13, 2026 · Last updated May 13, 2026

Summary

This study looks at whether a special ultrasound measurement of a large vein near the heart (the superior vena cava) can predict how a patient's body will respond to extra fluids during coronary artery bypass surgery. About 120 adults having this surgery will be monitored, and doctors will tilt the operating table to simulate giving fluids. The goal is to find a clear cutoff value that tells doctors who needs more fluids and who doesn't, potentially improving care and avoiding unnecessary fluid administration.
